    "incantation": "When you need to backfill only matching rows from a supported SQL source, run `gcloud datastream objects start-backfill` for the object with `--sql-where-clause` set to the filter, without the `WHERE` keyword.",
    "examples": [
      "gcloud datastream objects start-backfill <object> --stream=<stream> --location=<location> --sql-where-clause=\"t.key1 = 'value1'\""
    ],
    "gotchas": [
      "OBJECT (required): ID or fully qualified identifier of the stream object.",
      "--stream (required): Stream name; can be supplied in the fully qualified object identifier instead.",
      "--location (required): Resource location; can be supplied in the fully qualified object identifier instead.",
      "--sql-where-clause: SQL WHERE clause selecting included data, without the `WHERE` keyword. Supported only for SQL sources.",
      "Prerequisite: Partial backfill is supported only for SQL sources. Oracle, PostgreSQL, and MySQL support is being made available gradually; a request fails if the stream does not yet support the feature.",
      "Prerequisite: The object must not have `Pending` or `Active` status when initiating backfill.",
      "The partial backfill is on the specified object."
